Subject [jira] [Commented] (BCEL-279) Utility.methodSignature* throw ClassFormatException when converting binary names with generics.
Date Fri, 24 Feb 2017 22:22:44 GMT

    [ https://issues.apache.org/jira/browse/BCEL-279?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15883626#comment-15883626

Mark Roberts commented on BCEL-279:
-----------------------------------

The signature processing in BCEL has not been updated to support generic types.  I have been
trying to add some support (see https://issues.apache.org/jira/browse/BCEL-285) but the code
really needs a complete rewrite.  It should probably be modified to use sun.reflect.generics.parser.

> When I try the following, Utility class throws ClassFormatException:
> {code}
> String sig = "<T:Ljava/lang/Object;>(Lcom/google/common/io/ByteProcessor<TT;>;)TT;"
> Utility.methodSignatureArgumentTypes(sig, false)
> {code}
> The above signature actually exists in com.google.common.io.ByteSource in Google Guava.
> Utility.methodSignatureReturnType does not throw any exception but its return value does
not look valid.
> When I try this:
> {code}
> String sig = "<T:Ljava/lang/Object;>(Lcom/google/common/io/ByteProcessor<TT;>;)TT;"
> Utility.methodSignaturerReturnType(sig, false)
> {code}
> expected: java.lang.Object
> actual: T
> It seems that org.apache.bcel.generic.Type.java also has the same issue.
